To all 'whom t may concern Be it known that I, LoUIs A.` KLING, a citizen of the United States, residing in East Cleveland, county of Cuyahoga, State of Ohio, have invented certain Improvements in Clutch Mechanism, (being a division of application filed May 19, 1918, under Serial No. 768,595,) ofwhic'h thelfollowing is a specification. i y

My invention relates to certain .improvements in means forfoperating clutches, particularly those used in connection with door operating mechanismy of passenger cars such, for instance, as "illustrated and claimed in an application liled by me on the 19th day of May, 1913, under Serial UNO. 768,595,and of which this application is a division.

The object of -my invention is to simplify the construction of such mechanism and to provide means foroperating the door operhand.

In the accompanying drawings: Figui-e1 is a vertical sectional view of suiiicient of a door controlling mechanism to illustrate my invention; Fig. 2 is a plan View of sufficient of the mechanism to illustrate my invention; lfig. 3 is an inverted plan view of the worm wheel showing the clutch face; and Fig. 4 an enlarged sectional view of a portion of the disk and lthe shaft. l

Referring to the drawings, 1, in the present instance, is the platform of a passenger car.

2 is a casing inclosing the clutch mechanism.

8, 3 are rods connecting the` mechanism with the doors.

4 is a driving shaft coupled to a motor 5, illustrated in diagram, Fig. On this shaft 4 is a worm 6 and meshing with the worm is a worm wheel 7 mounted loosely on a vertical shaft 8. In the present instance, a sleeve 9 having a flange at the lower end carries this wheel and at the upper end there is a ring 10, which is secured to the sleeve and to the shaft. Thus, the wheel 7, while it is free to turn', is held against lon* gitudinal movement on the shaft.

VLocated under the worm wheel 7, in the present instance, is a disk 11 wllich has a keyway therein, and'secured to the shaft is a key 12 so that while the disk can slide face is recessed,

supported, in the present instance,

n specification of Leiters raient. ,Patented pee, '7, w15 original applicaiioiialed nay 19, lala, serial No.' 768,595.V Divided and '1913. serialivo. 797,255...

this application sled ociqberas, l

longitudinally `on the, shaft it must turn i therewith. 13 is .aV series of balls secured in sockets ln the` disk 11 .by an annular plate y14 which has holes through which the balls project.

The balls bear against akclutch facey on the under side of the wheel 7 and this clutch y asiat 15, forming 4pockets for the balls, so that when the balls 4are located in the pockets the wheel drives the disk and turns the sllaft.

In order tomove the disk to and from the wheel, I make theshaft 8k hollovT for a cerf tain distance and mountfa rod 16 in thisl sllaft. a Extending through a slot 17 in the shaft 8 is a pin 18 which is secured in the disk 11 and under this pin isr `a spring 19 n by a cross bar 20 mounted in the shaft 8. The -rod 16 rests upon the cross bar 18 and, when it is forced down, the diskV 11 is forced away from the wheel 7 so thatthe ywheel turns withoutturning the disk. -When the rod is Vreleased the spring 19, which bears against the pin 18, forces the disk toward the wheel 7 and the balls 18 engage the notched surface of the wheel, the disk and its shaft turning with the wheel. Thus, motion is imparted to the mechanism which opens and closes lthe doors. i

At the upper end of the tubular shaft, in.

the present instance, is a notched head 2l and the rod 16 has a head 22 projecting above the head 21 of the shaft. This can be pressed down by hand to release the disk 11 or it can be held down by a lever 23, which is shaped so as tofit over the llead 2l and has lugs 24, which enter notches in the head 21, and has a pivoted catch 25, the short arm of which extends under the head 21. When the leverA 23-is grasped by the hand, the shaft 8 can be turned by hand. I/Vhen it is wished to release the lever the long arm of the latch 25` is pressed toward the lever so as to release it, allowing it to be removed. When the lever is in position, it forces the rod 16 down so that the spring is compressed and the disk, with the balls, is clear of the driven wheel. By this arrangement,the shaft can either be turned by power or by hand, as, in

some cases, particularly in the operation ofr street cars, in some portions of the rollte, it is desirable to operate the doors by power` {.operatect.V
